What's A Pineapple Express?

SEATTLE - During a Pineapple Express, the jet stream --which acts like a steering force in controlling where weather goes -- will dip down into the tropics, and then carry a large batch of tropical moisture northeast into the Pacific Northwest.

Since many times the moisture has its origins in the area near Hawaii, the pattern got the name of "pineapple express."

These tend to be some of the wettest and warmest storms we see during the winter (they're usually responsible for most winter-time record highs), and a common culprit in causing our lowland flooding episodes, and this past week was no different.
